Adding mobile app specific redirect URLs to SIWSL

[DriesSchaumont]

Hi!

I was looking at using Simple Login as an identity provider for my Immich instance. Immich provides documentation on how to setup OAuth, and suggests to add app.immich:///oauth-callback to the Authorized Redirect URLs in order to use OAuth with the mobile app. However, Simple Login blocks these types of URLS being added because they are only allowed to be prefixed with https://.

Am I interpreting this correctly by saying that I would not be able to enable authentication using Simple Loging for immich (at least for use with the mobile app)?
Thanks in advance to anyone who could provide some insight!
